When we covered the Neptune Pine watch earlier this year, our first thought was that it looked like the smartwatch that tech lovers have been waiting for. That was immediately followed by a second thought – is this set of rough renderings ever going to lead to an actual watch we can buy? It hasn't happened quite yet, but things are moving in the right direction. Neptune has developed a working prototype and launched a Kickstarter campaign that has attracted a half-million dollars in pledges in just over two weeks.
